VMware ESXi 4.1 Kickstart Scripted Deployment with UDA (PXE BOOT)
Posted on 18.Mar 2011 by Ray Heffer in ESX, ESXi, Linux, Scripts & Commands, Tech Tips, Virtualisation, VMwareIf you are looking to deploy multiple ESX/ESXi servers then there are plenty of methods and tools out there, some more complex than others. There are vendor specific deployment products available such as HP Rapid Depuployment Pack (RDP) which uses Altiris, or alternatively there are free deployment tools such as ESX Deployment Appliance (EsleeDA) and Ultimate Deployment Appliance (UDA). UDA is my favorite tool for the job as it offers great flexibility such as the use of subtemplates (discussed later), and therefore this will be the basis of this article. It was created by Carl Thijssen and thanks to Mike Laverick of RTFM, it also supports ESX/ESXi deployments, and the latest build supports ESX/ESXi 4.1.
8.3 VCAP-DCA Study Guide – Configuring vMA for Logging
Posted on 07.Mar 2011 by Ray Heffer in ESX, ESXi, Linux, Scripts & Commands, VCAP-DCA, Virtualisation, VMwareIn this article I detail the steps required to configure your vMA as a Syslog server, and configure your ESX/ESXi hosts to send logging information to the vMA. Logging is often overlooked, but when managing multiple hosts it is far easier to send your logs to a Syslog server. I’m studying for the VCAP-DCA exam, and using vicfg-syslog is a requirement of the exam (Section 6.1) and the vMA is also essential to understand (Section 8.1). I hope my notes help you as they have helped me.

Linux commands and tips
Posted on 07.Jul 2005 by Ray Heffer in Linux, Scripts & Commands, Tech Tips
Checking kernel & CentOS version
To check which kernel version you are running use uname -r
# uname -r
To find out which CentOS (or RedHat) release is installed have a look at /etc/redhat-release
# cat /etc/redhat-release
Checking Disk Space
To check disk space used / free use the df command and it will display each volume. The -h switch turns the bytes reading into GB to make it more readable.
# df -h
If you want to check the size of a particular directory then use:
# du -sh /
